Vacuum cleaner

ABSTRACT

A vacuum cleaner including a housing with a dust container therein and a suction opening with a detachable connection of a suction hose to the opening. The housing having an outer wall aligned with the suction opening and the suction opening in an inner wall. The connector body of the suction hose having tubular end piece with a connecting cone insertable into the suction opening through both walls of the housing and into the dust container.

[0001] The invention relates to a connector for a vacuum cleaner fordetachable connection of a suction hose to a suction opening provided ina vacuum cleaner housing, wherein the connector with a tubular end piececan be inserted in the suction opening.

[0002] Such a vacuum cleaner is known from DE 42 40 913 A1. In the knownvacuum cleaner there is provided a vacuum cleaner hose which isdetachably coupled to a connector via a coupling element. The connectorhas a tubular end piece which can be inserted in a suction opening in avacuum cleaner housing. The connector has a circular cross-section andis thus rotatably mounted in the vacuum cleaner housing.

[0003] It is the object of the invention to improve a connector of thetype described initially.

[0004] This object is solved according to the invention by the fact thatthe connector can be guided through a first outer and a second innerwall of the vacuum cleaner housing.

[0005] The connector according to the invention provides a particularlystable and secure connection between the vacuum cleaner hose and thevacuum cleaner housing.

[0006] In an advantageous development of the invention, the connectorwith a connecting cone dips in a sealing fashion into a dust container.By means of this measure, the connector is on the one hand fixedlyconnected to the dust container, thus for example in the case of a dustbag, to its filter cardboard, but despite this the dust bag can bechanged even when the connector is inserted since the connector does notdip into or does not dip deeply into the dust bag.

[0007] A further advantage of the invention is that the connector can befixed in a region between the first and the second wall. As a result ofthis arrangement, a high stability is achieved.

[0008] In an advantageous further development, the connector has asealing lip which sits on the outside of the second wall and by whichmeans it can be fixed on the second wall.

[0009] The connector preferably has at least one catch lug by whichmeans the connector can be fixed on the inside of the first wall. Thestability of the connector is also increased by this measure.

[0010] In an advantageous development of the invention there is provideda gripping element accessible from the outside of the wall by whichmeans the at least one catch lug can be pressed backwards and theconnector can be withdrawn from the vacuum cleaner housing.

[0011] The gripping element is advantageously formed by a catch hook onwhich the catch lug is respectively arranged.

[0012] The arrangement of a gripping recess on the catch hook isespecially advantageous. The connector can thereby be conveniently andrapidly separated from the vacuum cleaner housing.

[0013] The invention is explained in further detail below in anexemplary embodiment with reference to the drawings. In the figures:

[0014]FIG. 1 is a longitudinal section through a connector inserted in avacuum cleaner housing,

[0015]FIG. 2 shows the connector in a longitudinal section turnedthrough 90° about the longitudinal axis of the connector with respect tothe longitudinal section shown in FIG. 1 and

[0016]FIG. 3 shows a plan view of the connector.

[0017] A vacuum cleaner has a vacuum cleaner housing 1 that for example,forms the lower part of the complete housing of the vacuum cleaner. Thevacuum cleaner housing comprises a wall 2 to which a wall 3 is connectedat an angle. The wall 3 serves for example as the front apron of thevacuum cleaner below which the user can grip to lift up the vacuumcleaner. Inside the vacuum cleaner housing 1 a filter bag 4 is affixeddirectly behind the wall 2 as a dust space. A filter cardboard 5 extendsin the vicinity of the wall 2.

[0018] An end piece 7 of a connector 8 projects into an opening 6 of thefilter cardboard 5. At its free end the end piece 7 has a sealing cone 9which is exactly the same size as the opening 6 and ends approximatelyflush with the side facing the inside of the filter bag 4 so that itdoes not project into the filter bag 4.

[0019] The end piece 7 also has a circumferential sealing lip 10 whichensures that the dust space with the filter bag 4 is sealed towards theoutside.

[0020] The connector 8 has a connecting piece 11 with which it isconnected to a suction hose. The connecting piece 11 becomes the endpiece 7 and penetrates through the outer wall 3. It thus impartsstability to the housing apron formed by the wall 3.

[0021] The connector 8 is held on the side of the wall 3 facing the wall2 by means of catch lugs 12 (FIG. 2) which are attached to the outsideof catch hooks 13. The catch hooks 13 serve as gripping elements so thatthe connector 8 can be withdrawn from the opening 6.

[0022] The catch hooks 13 interact with the sealing lip 10 such that theconnector 8 is fixed slip-free between the walls 2 and 3. In order thatthe catch hooks 13 can be simply pressed together during removal of theconnector 8 from the vacuum cleaner housing, gripping recesses 14 arearranged on the catch hooks 13. When the catch hooks 13 are pressedtogether by pressing on the gripping recesses 14, the catch hooks 12 aremoved to a distance apart from one another which is less than thediameter of the opening for the connector 8 in the wall 3. The connector8 can then be pulled out from the walls 2 and 3, exposing the opening 6.

[0023] At the free end of the connector 8 said connector is detachablyor non-detachably connected in an inherently known fashion to an endpiece of a suction hose. A detachable connection between the connector 8is known for example from DE 42 40 913 A1.

[0024] The invention provides a connector 8 for a vacuum cleaner housingwhich is held between walls 2 and 3 of the vacuum cleaner housing. Thewall 3 forms a front apron of the vacuum cleaner and can be gripped fromits underside by a user such that it is suitable for carrying saidvacuum cleaner.

[0025] The connector 8 is fixed between the walls 2 and 3 by means of asealing lip 10 and the catch lugs 12. In this case, the connector 8 witha sealing cone 9 dips into a filter cardboard 5 such that the filter bag4 can be removed even when the connector 8 is inserted.
